Composite structure for coastal steel sheet pile, cofferdam and rotary jet grouting wall and construction method
The invention discloses a composite structure for a coastal steel sheet pile, a cofferdam and a rotary jet grouting wall. The structure is arranged on a coastal beach land; the coastal beach land comprises a permeable layer and an impervious layer located below the permeable layer; the composite structure comprises a cofferdam and rotary jet grouting wall assembly and double-row steel sheet piles; the cofferdam and rotary jet grouting wall assembly is arranged between an open sea and a foundation pit; the double-row steel sheet piles are vertically arranged between the cofferdam and rotary jet grouting wall assembly and the foundation pit; and the double-row steel plate piles comprise a first layer of steel plate piles, a second layer of steel plate piles, steel pipe supports and a sand soil layer. According to the composite structure for the coastal steel sheet pile, the cofferdam and the rotary jet grouting wall, the double-row steel plate piles are arranged between the cofferdam and rotary jet grouting wall assembly and the foundation pit, and the double-row steel plate piles, the water retaining cofferdam and the high-pressure rotary jet grouting diaphragm wall form the composite structure, so that water is jointly retained, the stability of the foundation pit is guaranteed, the difficulties that a construction site is narrow, the construction period is short, and the foundation bearing capacity is low are overcome, and conditions for sluice dry land construction are rapidly created.
本发明公开了一种用于沿海的钢板桩、围堰及旋喷墙的组合结构，设置在沿海滩地上，所述沿海滩地包括透水层和位于所述透水层下方的不透水层，所述组合结构包括围堰及旋喷墙组件和双排钢板桩，围堰及旋喷墙组件设置在外海与基坑之间，双排钢板桩竖直设置在所述围堰及旋喷墙组件与所述基坑之间；所述双排钢板桩包括第一层钢板桩、第二层钢板桩、钢管支撑和砂土层，本发明通过设置在围堰及旋喷墙组件与基坑之间设置双排钢板桩，以跟挡水围堰、高压旋喷防渗墙形成组合结构，共同挡水及确保基坑稳定，克服了施工场地狭小、施工工期紧张、基础承载力低等困难，快速创造水闸干地施工的条件。
